Thread: Harley Quinn's Revenge title update

I have Batman AC US TB and everything works, campaign and DLCs. But, the one problem I have is with Harley Quinn's Revenge. Every time I choose it, there is always an error that says I need to install updated titles. I installed the 1.04 patch but I still have the problem. Any ideas? Thanks.

Never mind I got it! If anyone else has this problem my solution was that I replaced the TB eboot and sfo with the originals.
After that I loaded Batman from MM I applied ZombieKillah's 1.04 patch.
Finally I launched Batman and now I am able to play HQ's Revenge flawlessly.
